"One does not meet oneself until one catches the reflection from an eye other than human." - Loren Eiseley. I am not a birder or bird expert (or somebody who pretends to be the one). I would rather spend hours, days or even weeks with one species, in some cases one bird, then try to see and count them all. Learning about animal behavior is the most important part of my passion in my studies of a few selected birds. So, if you see any identification mistakes please let me know. Especially if you feel that you can bet your wife or mother-in-law on your ID. No, I will not try to collect the prize if you are wrong. And do not bet your girlfriend, wife or mother-in-law in hopes you can get rid of one easily. I will gratefully appreciate all your help whether it was a typing mistake or lack of knowledge on my part. Best regards, Mark.
